IMPROVEMENT IN SPlNNlNG-MACHINES..

Specification forming part of Letters Patent No. 115,676, dated June 6, 1871.

- one set of the reverse-motion twistingtubes for intermediate spinning or twisting between the draft-rollers. Fig. 2 shows a side elevation of the machine with the arrangement of various bands and shafts for communicating motion tc the draft rollers, twisting-tubes, Src., and the ratchet mechanism for taking up the yarn and forming the cop on the spindle. Fig. 3 shows an end view of the same. Fig. 4 shows a section through one of the rear or left-motion twisting-tubes. Fig. 5 is a similar section through the front or right-motion twisting-tube. 4

Our invention relates to wool-spinning for domestic manufacture and use; and the object of our improvement is to facilitate the winding operation, and it consists in the construction, arrangement, and combination of the mechanism for building up the yarns on the cops or bobbins.

.To enable others. to make and use our improvement, we will describe it more in detail, referring to the drawing and the letters there- We make the frame of our spinner of hard wood, of such proportions and size as will accommodate ten or twelve spindles, more or less, with the band-cylinder A for driving the vertical spindles a aattached to two of the posts B B. Other shafts, O D E, with their` gangs of pulleys e f g, are so arranged as to drive the twistingftubes b and d and the three sets of draft-rollers E I J by means of certain bands, and give them the proper speed, so that the roving on our continuous carded wool-roll is fed in and partially twisted or spun by the tubes b and d revolving in opposite div rections in the spaces between the drawing and feed rollers, so that when it is conveyed to the vertical spindle a to complete the twisting ofthe yarn it is in the most perfect and uniform condition.

The intermediate twisting or partial spinning given to the wool between the draft-rolls equalizes the ibers, so that there are no weak places, and a very superior article of yarn isl produced, and the spinning requires much less attention, as there is scarcelyT any liability of the wool-roll pulling apart or the yarn breaking;

The twisting-tubes l and d, as shown in Figs. 4 and 5, are very simple in their construction, each being formed with a band-pulley and journals, and with a conical opening, X, through each longitudinally, and slender yielding shrugs y y to clamp the wool-roll or slightly twisted yarn as it passes to the ver tical spindle a.

The mechanism herein shown for building up the yarn andformin g the cop or bobbin on the spindle is very simple and efficient. It

consists of two sliding vertical frames, K and L, working one in the other, the frame K be ing provided with racks W YV, operated by pinions o u and a ratchet t, pawl u, lever It, and coupling-bar S to give the gradual rise to the rail M to guide the successive layers of yarn higher and higher upon the spindles. The ,sliding frame L is provided with a rail, M, on which the projecting ring-guides N are secured, and is moved up and'down by the cams T T on the shaft U to distribute the yarn evenly to form the conical layers on the spindle h, which pass up through the table or rail M and ring N.

What we claim as our invention, and desire to secure by Letters Patent, is

The arrangement of the sliding frames K and L, rail M, the racks and pinions W and 0, the ratchet mechanism R t, the couplingbar S, and the cams T T,l substantially as and for the purposes specified. A

In testimony whereof we hereunto subscribe our names.
